Features:

* It Plays as Hard as it Works - Win 8.1 gives you the power to quickly browse, watch movies, play games, polish your resume, and pull together a killer presentation — all on a single PC. Now you can organize up to three apps on your screen at once in a single view.

* The Start Screen - Personalize your Start screen with your favorite news, friends, social networks, and apps. Customizable colors and backgrounds and four different sizes of tiles make your device as unique as you are.

* The Apps you Want - In addition to great built-in apps for email, people, photos and video editing – you can also download thousands of popular apps from the Win Store, including Netflix, ESPN, Skype and Halo: Spartan Assault.

* Security - Stay up to date and more secure with Win Defender, Win Firewall, and Win Update.

* Speed - Win 8.1 starts up faster, switches between apps faster, and uses power more efficiently than previous versions of Win, including Win 7.

* Multitasking Made Easy - It’s easy to do more at once. Snap multiple apps side by side in a single view for easy multitasking.

* Mouse, Keyboard—and now Touch - Win 8.1 works harmoniously with various types of devices, including touch, mouse-and-keyboard, or both. Whatever kind of device you have, you'll discover fast and fluid ways to switch between apps, move things around, and go smoothly from one place to another.

* You Keep all your Files - If your PC is running Win 7, your files, apps and settings will easily transfer to Win 8.1 Pro.

* You Keep Familiar Programs - Programs that run on Win 7 will run on Win 8.1 Pro.

What Win products does GVGMall sell?
We offer genuine Win 10 Home, Win 11 Home, Win 10 Pro, Win 11 Pro, Win Enterprise LTSC, and Win Server licenses.
Can a Win 11 key activate Win 10?
Yes. A Win 11 Pro key can activate both Win 11 Pro and Win 10 Pro systems.
What is Win Enterprise LTSC?
Win Enterprise LTSC is a Long-Term Servicing Channel version designed for increased stability and lower resource usage. Ensure you install the official retail version, not the evaluation edition.
What are Win N/KN versions?
These are versions for the European and Korean markets that do not include Win Media Player. Our standard Win keys may not work on these versions.
How do I find my purchased Win key?
Log into your GVGMall account, go to "User Center" > "My Purchased Orders", and click "View Code".
How do I activate Win 10 or Win 11?
Go to "Settings" > "Update & Security" > "Activation", click "Change product key", and enter your Win product key.
Can I use the key during Win installation?
No. During installation, please select "I don't have a product key". After Win is fully installed, activate it via "Settings" > "Activation".
Can a Win Pro key directly upgrade a Win Home system?
No. A Win Pro key is for activating an already installed Pro system. You must first upgrade or reinstall to a Win Pro system.
What does error code 0xC004F050 mean?
This usually indicates a mismatch between your system version (e.g., Win 10/11 Home) and your key (e.g., Win 10/11 Pro). Please install the correct version first.
Alternatively, you can try our upgrade method (Steps 2 and 5 are important):
1. Restart your computer.
2. Try using these 5 upgrade keys:
  • 2K8JW-BNRW7-J7WDQ-6V6RG-H8RC6
  • 8NXF2-GVCHY-W37GQ-27Y24-2KCKG
  • YPPGJ-YRNCR-QCJGV-K9CYK-XKXTT
  • XWNYM-YMPF9-BJ6MY-3CRTC-KW3GT
  • DBH4C-J7N6X-YFY3P-Y84PB-7MH26
You will receive a prompt to start the upgrade or that the key is invalid.
If a key is invalid, try another one, then restart your PC.
If the system has been upgraded to Pro, use the key you purchased to activate it.
How do I fix errors like 0x80072f8f, 0x80072ee2, or 0x803F7008?
For such error codes, please contact our customer support.
Can I activate a Win Enterprise LTSC Evaluation edition?
No. Our keys cannot activate evaluation editions. Please download and install the official retail version of Win Enterprise LTSC from: https://massgrave.dev/windows_ltsc_links
How do I activate a Win Server Evaluation edition?
Use PowerShell to convert it to a retail edition, then activate it with your key. For example:
Launch PowerShell as an Administrator.
dism /online /get-currentedition
Press ENTER.
dism /online /get-targeteditions
Press ENTER.
dism /online /set-edition:serverstandard /productkey: yourkey /accepteula
Press ENTER.
(Note: Replace yourkey with your actual key without brackets).
